XHT-5 Safety Self-Test High Performance Ignition System Device Flam
Scanner For Electric Power, Metallurgy
NHT Flame detection device of power station boiler of large
combustion equipment of furnace safety supervisory system and a
variety of industrial furnace,the key equipment of burner flame
detection.The device according to the physical properties of the
combustion flame detection,When the flame burning state does not
meet the normal condition or flameout,it will show signal by some
mode (Switch quantity and analog quantity),as logic judgment of the
fault alarm or furnace safety supervisory system(FSSS).
Technical advantages:
Using the latest software and hardware identification technology,
with high reliability.
With a self-test function, and has higher safety.
Adapt to all types of fuel, including gas, fuel, coal and other
fuel types.
Detection mode, including ion type, light type and image type.
Applications:
NHT Flame detection device is widely used in electric power,Iron
and steel, metallurgy, petrochemical and other industries a variety
of boiler,burner flame detection, and also can be applied to
various occasions the need for flame detection.
Specifications:
Sr. | Name | Model | Description |
1 | Falme scanner | XHT-1 | Contact type flame detector |
2 | Falme scanner | XHT-2 | Micro flame ionization detector |

XHT-5 Visible light type flame detector
1 basic configuration:
Consist of probe, flame detector and field regulator(choose ),
Widely used in power plants, metallurgy, petrochemical, building
materials and other fields of all kinds of fuel, coal burning flame
detection, The digital processing technology and the pattern
recognition software, hardware, to quantization processing to
target flame, improve the accuracy of the detection, independent
power supply, reduce the system risk, self-checking function, safe
operation.
2 Performance parameters:
Working principle:Target flame by the lens group focused , then
through the optical fiber to pretreatment circuit board, Visible
light signal is converted to electric signal , then make flame
intensity and pulse frequency to be digital processing, finally to
flame detector , the CPU of flame detector collect the signals from
probe , After treatment, calculate, display the flame intensity and
pulse frequency respectively by the digital tube,at the same time
display the flame intensity by light pipe , according to
predetermined set of fire on , fire off standard toidentify ,
finally do the corresponding signals and instructions.
There are 2 types of flame detector :
Instrument type , Chasis type
